ATTORNEY Patented June 11, 1963 3,093,289 CARTON WITH INTEGRAL PARTITION MEMBER Albert Reisman, Philadelphia, Pa., assignor to J. Reisman & Sons, Inc., Pennsauken, N.J., a corporation of Pennsylvania Filed Apr. 27, 1961, Ser- No. 105,938 1 Claim. (Cl. 229-27) This invention relates to a carton and blank therefor, and more particularly to a blank from which a carton adapted to receive food products may be made.

It has been conventional heretofore to make a carton from a blank and insert a removable partition wall so as to divide the carton into two compartments. The necessity for providing a separate partition wall is expensive, time consuming, and reduces the production rate at which the cartons may be filled.

I have discovered that the above mentioned defects of the cartons made heretofore may be overcome by providing a partition wall which has one end integral with a side wall of the carton. The blank for the carton includes a U-shaped slit in a portion thereof corresponding to a side wall of the carton. A score line is provided across the free ends of the U-shaped slit equidistant from the ends of the portion of the blank corresponding to the side wall of the carton. The apparatus for assembling the blank into a carton will include means for automatically positioning the partition wall out of the plane of the portion of the blank corresponding to the side wall so that said partition wall extends transversely of the carton between the side walls thereof.

It is an object of the present invention to provide a novel carton blank.

It is another object of the present invention to provide a novel carton formed from a blank wherein a partition wall extending transversely of the carton has an end which is integral with a side wall of the carton.

It is still another object of the present invention to provide a novel carton which eliminates the cost of a separate partition wall, increases the speed of filling the cartons, and thereby decreases the cost of filling cartons with material.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentali-ties shown.

FIGURE 1 is a plan view of the blank of the present invention.

FIGURE 2 is a perspective view of the carton of the present invention in assembled disposition.

FIGURE 3 is a transverse sectional view taken along lines 3-3 in FIGURE 2.

Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIGURE 1 a blank designated generally as 10. The blank d is adapted to be shaped into a carton designated generally as 11.

The blank includes a portion adapted to form a bottom wall 12 of the carton I11, portions adapted to form side Walls .14 and .16, and portions adapted to form end walls 18 and 20.

The bottom wall 12 and the side wall 14 are separated by a crease line 22. The bottom wall 12 and the end wall 20 are separated by a crease line '24. The bottom wall 12 and the side wall 16 are separated by a crease line 26. The bottom wall 12 is separated from the end wall 18 by a crease line 28. When the carton 11 is assembled from the blank 10', the blank 10 will be folded along the crease lines 2228 so that the side and end walls will v be upright with respect to the bottom wall r12 as shown more clearly in FIGURE 2.

The side wall 14 is provided with a slit 30 which receives a tongue 32 on the end wall 21 in the assembled disposition of the carton I l. The side wall 14 is provided with a slit 34 adapted to receive the tongue 36 on the end Wall 18 in the assembled disposition of the carton ll.

The side wall 16 is provided with a slit 38 adapted to receive the tongue 40 on the end wall 18 in the assembled disposition of the carton 11. The side wall 16 is also provided with a slit 42 adapted to receive the tongue 44 on the end wall 20 in the assembled disposition of the carton 11.

A top wall 46 is integrally connected with the end wall 18 and is separated therefrom by the crease line 47. A top wall 48 is integrally connected with the end Wall 20 and is separated therefrom by the crease line 49.

A U-shaped slit 50 is provided in the side wall '16. The slit 50 extends through the thickness of the side wall 16. A score line 52 extends across the free ends of the U-shaped slit 50. A score line 52 is equidistant from the end edges of the side wall 16. The end edges of the side wall l6 are those edges which coincide with the crease lines 24 and 28.

The U-shaped slit 50 and the score line 52 define a partition wall 54. The partition wall 54 is integrally connected to the side wall 16 along the score line 52. As distinguished from the slit 50, the score line 52 is a cut extending only partially through the thickness of the side wall -16. The partition wall 54 has a length corresponding to the width of the bottom wall 12. The partition wall 54 remains in the plane of the side wall :16 until it is manipulated to the position shown in [FIGURE 2 during the assembly of the carton 11.

The movement of the partition wall 54 to the position shown in FIGURE 2 will be accomplished automatically by apparatus forming the subject matter of a copending application. A detailed explanation of such apparatus is not required for an understanding of the present invention.

The carton 1.1 of the present invention is particularly adapted for packaging rows of pretzels shown in phantom in FIGURE 3 and designated by the numeral 56. A row of pretzels will be provided on each side of the partition wall 54. After a row of pretzels has been provided on each side of the partition wall 54, the carton '11 will be enclosed within a transparent cellophane wrapper 58.

Since the partition wall 54 is provided with one end integral with the side wall 16 and is a .part of the blank 10, the cost of separate partition walls has been elimi nated. Since the partition wall 54 is manipulated to the position shown in FIGURE 2 by automatic machinery, the cost and assembly time associated with the insertion of separate partitions has been eliminated. Since the carton r11 arrives in the form shown in [FIGURE 2 at the assembly station where pretzels are inserted into the carton, the speed of assembly has been materially increased.

The blank 16 is preferably made from a semi-stiif paper. The material of the blank 10 may be varied so long as it is capable of having crease lines facilitating the assembly of the carton into its assembled disposition. While the partition wall 54 is provided with one end integrally connected to the side wall 16, it will be obvious that the partition wall could alternatively have one end integrally connected with the side wall '14. Also, it will be obvious that the partition wall 54 may be utilized in cartons having a shape which differs from the shape shown in FIGURE 2. For example, the partition wall 54 could be utilized in cartons which are square rather than rectangular in shape.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.

I claim:

A carton comprising a rectangular bottom wall having a length more than twice its width, square end Walls integral with said bottom wall and at right angles thereto, side walls integral with the long side edges of said bottom wall and with one edge of each of said end walls, the center of said side walls having a height equal to the height of said end walls, two pairs of equal U-shaped cutouts in each of said side Walls, each pair of said U-shaped cutouts extending downward from the top edge of its associated side wall on opposite sides of the center of said side wall, the lowermost portions of said U-shaped cutouts being in a plane parallel to said bottom wall, paper locks integral with said end walls interconnecting said side and end walls for maintaining said side and end walls upright with respect to said bottom wall, a partition wall having long side edges extending between said side walls at the center thereof and adapted to separate equal rows of pretzels extending from said partition to said end Walls between said side walls, said partition wall being located below the lowermost portion of said U-shaped cutouts on said side walls, said partition wall having short end edges, one short end edge of said partition wall being integral with one of said side walls along a fold line the extension of which is perpendicular to said bottom wall, said fold line on said one side Wall having a length less than the distance between the lowermost portion of said U-shaped cutouts and the joint between said side wall and said bottom wall, said one side wall additionally having an aperture coextensive with the dimensions of said partition wall, one edge of said aperture being coextensive with said partition wall fold line, and a pair of top sup ports extending between the top edges of said side walls adjacent the top edges of said end walls and adapted to hold the pretzels in place.
